//	An example of using Fl_Menu_Bar's add() to dynamically create menubars
//
//	Menu bars can be created several ways. Using add() allows
//	dynamically creating a menubar using a 'pathname' syntax.
//	Use if you're creating items dynamically, or if you're making 
//	menubars by hand (as opposed to using fluid), as it's easier
//	to type and read. 
//
//	In this case we're using one callback for all items, 
//	but you can make unique callbacks for each item if needed.
